ABC World News Tonight with Charles Gibson going HD in September

September 8th is gearing up to be quite the day for high-definition debuts. Earlier this year we learned that the Ellen Degeneres Show would be making its HD premiere on that very day, and now we've learned that ABC World News Tonight with Charles Gibson will be doing the same a few hours later. Hot on the heels of the CBS Evening News making the high-def leap comes an ABC spokeswoman to curve the coverage away from that other network. According to her, said program is scheduled to go HD "the week of September 8th," though no other details were revealed. Better enjoy that edge while it lasts, Katie / Brian.
